Setting Up CFM

The steps required to set up Connectivity Fault Management (CFM) are:

• Set up Maintenance Domains (MD).
• Set up Maintenance Associations (MA), also known as Maintenance Entity Groups (MEG).
• Set up Maintenance association End Points (MEP).

Viewing CFM Summary

The CFM summary can be displayed whether the remote device context has been set or not.

If the remote device context has not been set, the CFM library version for all remote devices will be displayed. If the remote device context has been set, then only the information related to the selected device will be displayed.

To view CFM summary

1. Access the page SOAM ▶ CFM ▶ Summary.
   A list of all CFM instances and their settings is displayed.

For more information on specific parameters, refer to the following table.

CFM Summary (SOAM ▶ CFM ▶ Summary)

Configuring the CFM library

The CFM library can be configured (either v1 or v2) to be used for the selected remote device.

To configure the CFM library

1. Access the page SOAM ▶ CFM ▶ Summary.
   A list of all CFM instances and their settings is displayed.

2. Click the Library of an exiting CFM instance to display the SOAM library configuration window.

3. Select the library version then click Apply.

For more information on specific parameters, refer to the following table.

Viewing CFM Instances

To view CFM instances

1. Access the page SOAM ▶ CFM ▶ Stack.
   A list of all CFM instances and their settings is displayed.

For more information on specific parameters, refer to the following table.

CFM Stack (SOAM ▶ CFM ▶ Stack)

There are eight pseudo MDs defined by default, one for each level, named Y.1731 level 0 to Y.1731 level 7. These MDs exist only to simplify the integration of MEGs for Y.1731 with the CFM MIB, which requires MDs. The Y.1731 protocol uses MEG-IDs, which are MAIDs without an MD name. User interfaces show the pseudo MD name, but this name is not included in the Y.1731 CCM's MEG-ID.

Setting Up Maintenance Domains (MD)

To set up a Maintenance Domain

1. Access the page SOAM ▶ CFM ▶ MD.
   A listing of all existing Maintenance Domains is displayed.

2. Click the Add button to create a new Maintenance Domain.
   You can also click the Name of an existing Maintenance Domain to either Apply, Reset or Delete it.

3. Complete the required fields, then click Apply.

For more information on specific parameters, refer to the following table.

Maintenance Domain (SOAM ▶ CFM ▶ MD)

Deleting a Maintenance Domain (MD)

To delete a maintenance domain

1. Access the page SOAM ▶ CFM ▶ MD.
   A listing of all existing Maintenance Domains is displayed.

2. Click the name of the MD instance to be deleted.

3. Click Delete.

   ---

   CAUTION: Deleting an MD will also delete all instances (e.g. MA/MEG) that use this MD.

   ---

Setting Up Maintenance Associations (Maintenance Entity Groups)

Before setting up an MA (also referred to as a MEG), you must first set up the MD to which you want the MA/MEG to belong. Maintenance Associations (MA) are discussed in IEEE 802.1ag; Maintenance Entity Groups (MEG) are discussed in ITU-T Y.1731.

To set up a Maintenance Association or Maintenance Entity Group

1. Access the page SOAM ▶ CFM ▶ MA/MEG.
   A listing of all Maintenance Associations / Maintenance Entity Groups is displayed.

2. Click the Add button to add a new Maintenance Association or Maintenance Entity Group or click the Name of an existing Maintenance Association or Maintenance Entity Group to apply, reset or delete it.

3. Complete the required fields, then click Apply.

For more information on specific parameters, refer to the following table.

Maintenance Association (SOAM ▶ CFM ▶ MA/MEG)

To delete a Maintenance Association (Maintenance Entity Group)

1. Access the page SOAM ▶ CFM ▶ MA/MEG.
   A listing of all Maintenance Associations / Maintenance Entity Groups is displayed.
2. Click the name of the Maintenance Association or Maintenance Entity Group to be deleted.
3. Click Delete.

   ---

   CAUTION: Deleting a MA/MEG will also delete all instances (e.g. MEP) that use this MA/MEG.

   ---

Setting Up Maintenance Association End Points

Before setting up a MEP, you must first set up its MA/MEG. Maintenance association End Points (MEP) are discussed in IEEE 802.1ag.

To set up a Maintenance association End Point

1. Access the page SOAM ▶ CFM ▶ MEP ▶ Configuration.
   A listing of all Maintenance association End Points is displayed.

2. Click the Add button to add a new MEP or click the MEPID of an existing MEP to apply, reset or delete its settings.

3. Complete the required fields, then click Apply.

   ---

   Note: Users can undo the current changes by clicking Reset to restore the values prior to making any changes. The Delete operation is described on the next page.

   ---

For more information on specific parameters, refer to the following table.

Maintenance association End Point (SOAM ▶ CFM ▶ MEP ▶ Configuration)

To delete a Maintenance association End Point

1. Access the page SOAM ▶ CFM ▶ MEP ▶ Configuration.
   A listing of all Maintenance association End Points is displayed.

2. Click the MEPID of the MEP to be deleted.

3. Click Delete.

Viewing MEP Status

To view maintenance association end point (MEP) status

1. Access the page SOAM ▶ CFM ▶ MEP ▶ Status.

   A listing of all MEPs is displayed, along with their status codes and details.

   The total number of MEPs found in the system is given in the lower left corner of the page, as well as the index values of the items currently displayed on-screen (for example, [1-25] of 54). Use the page navigation links in the lower-right corner of the page to move between the pages of results.

2. (Optional) To limit the view to only certain MEPs, enter a value on which to filter, then click Search. You can filter by the MEP name, MEPID, Database, RDI or R-CCM status code value. If the MA/MEG was created using a VCA-VLAN/VCE, you can filter by the MEP Index, MEPID, Database, RDI, MAC, R-CCM, E-CCM, X-CCM, AIS, EPL, EDM, C-LOS, C-FDI, C-RDI, N-SLM and F-SLM status code values.
